Informal French Expression

Usage notes: Have you ever been truly, madly, deeply in love? Then the French expression vivre d’amour et d’eau fraîche or se nourrir d’amour et d’eau fraîche might describe how you felt, as if you didn’t need food, friends, family, or anything else but your love and maybe a bit of water to survive.

More generally, vivre d’amour et d’eau fraîche means to live a carefree existence, with no worries or responsibilities. It’s often used in the negative with people who refuse to grow up.
